Why is coffee in the genitive case
This is because 'coffee' is the direct object in a negative statement, which requires (most of the time) the use of genitive case.
'Dyrektor lubi tę kawę' - Accusative
'Dyrektor nie lubi tej kawy' - Genitive
Thank you. I forgot about the negative requiring genitive. A lot of rules, little room in my brain.
Dyrektor in polish can refers to the boss or CEO, or president of the company
And this is his problems!
